Energy-Saving Design Strategies for Non-Residential Structures in Pakistan’s Arid Lowlands

Abstract

The Buildings' Energy measures and savings in Pakistan are of paramount importance. It has been discussed for many years but attaining a coherent solution is still one of the main tasks. Energy efficiency in buildings is an important objective of energy policy and strategy in Pakistan. The HAP 4.0 Software was used for this research to calculate energy and simulated analysis of the Specific climate Zone of Multan (Subtropical continental Lowlands arid). This study aims towards for Comfort zone using cooling design strategies that predict the use of building control depending on climate, orientation of building, and material of building. The results showed that Adaptive Comfort Model ASHRE-2005 for 8760 hours per year achieving Sun shading of windows, cooling, and dehumidification increases by 25.1% and 42.1 % of Comfortable hours. Energy simulation presented that building load decreases using the double-glazed window from the East and west sides and applying such design Strategy increases the 14.8% of Comfort hours without additional investment.
